How to increase screen time on Xiaomi smartphones: from basic settings to hidden MIUI chips

Screen time on Xiaomi is one of the key indicators of autonomy that users care about most. Unlike total operating time, which includes sleep periods, screen time shows how much the device was actually used actively, whether to watch videos, games, messengers or navigation. If your smartphone runs too fast when the display is turned on, the problem lies not only in the battery capacity, but also in the optimization of the system.

In this article, we will discuss 7 working methods, how to increase screen time on Xiaomi, Redmi and POCO — From obvious energy saving settings to little-known firmware tricks MIUI. It is important to understand that the result depends on the device model, the system version and individual use cases. 13 Pro AMOLED-display and processor Snapdragon 8 Gen 2 increase may be made up to 30%, On the budget Redmi Note 12 — near 10-15%. We tested the methods on current versions. MIUI 14 HyperOS, but most tips are suitable for old firmware.

Before you get to the settings, check the current screen time: go to Settings → Battery → Battery Use. This shows the screen activity schedule (usually highlighted in green or blue). If the value is below 4-5 hours for flagships or 3-4 hours for budget models, it is time to optimize the system.

1. Optimization of screen settings: brightness, refresh rate and timeout

The display is the main consumer of power in a smartphone, and even minor changes in its parameters can significantly affect autonomy, starting with the basic settings that are available in any Xiaomi device:

• 🌞 Adaptive Brightness: Turn it off in Settings → Display. → Brightness: Automatic adjustment often overstates brightness, which reduces screen time by 15-20%. Set a fixed value in the range 30-50% — This is enough for comfortable use in the room.
• 🔄 Update frequency: On flagships (Xiaomi) 13/14, POCO F5) accessible 60, 90, 120 or 144 Hz. Switch to the next one. 60 Hz in Settings → Display. → Update rate. It'll reduce the smoothness of animation, but it'll increase screen time by 25-30%.
• ⏱️ Screen timeout: Reduce the time before the display is turned off 15-30 seconds in Settings → Display. → Sleeping after. This is true if you often forget to lock your phone.
• 🌙 The dark subject and AMOLED-Optimization: Include a dark theme in Settings → Display. → Dark theme, on devices with AMOLED-screens (e.g. Xiaomi) 12T or Redmi K50) Black pixels are not illuminated, which saves up to 10% of charge.

For models with LCD-displays (e.g., Redmi) 10A or POCO M5) A dark theme won't do that, but it will still reduce the load on the GPU. Also note the brightness of the light in the dark: MIUI There is a separate setting for night mode, which may conflict with the basic brightness parameters.

⚠️ Note: On some devices (e.g. Xiaomi) 11T Pro) Forced reduction of refresh rate to 60 Hz can cause artifacts in games. In this case, use adaptive mode with a limit of 90 Hz.

Configuring energy saving modes and background limitation

MIUI offers several preset energy saving profiles, but their standard settings are often redundant or insufficient. The best option is to manually adjust to your tasks. Go to Settings → Battery → Battery Mode and select Balance (or Energy Saving if autonomy is critical).

• 🔋 Background Limitation: Turn on Background Limits and select Strictly.This will block unnecessary application activity when the screen is off.
• 📱 Optimization MIUI: Activate Deep Optimization (not available on all models) This feature aggressively closes background tasks, but can cause delays when switching between applications.
• 🔄 Automode: Turn off Automode Selection as the system often switches to Performance without the need to.

For advanced users, the hidden mode "Ultra Battery Saver" is available, which activates at a critical charge level (usually below 5%).

1. Go to Settings → Battery → Battery Mode → Energy Saving.
2. Click on the three dots in the upper right corner and select Additional.
3. Activate Ultrasonic Mode (the name may vary depending on the version of MIUI).

In this mode, all background processes, notifications and performance are turned off, but screen time can increase by 1.5-2 times. For example, on the Redmi Note 11 Pro+ at 10% charge in ultra mode, it was possible to last another 1.5 hours of active use instead of the usual 20-30 minutes.

3.Application management: what drains the battery in the background

Many programs continue to work after closing, consuming processor and battery power, especially social networks (Facebook, Instagram), instant messengers (WhatsApp, Telegram) and games. To identify the main culprits, go to Settings → Battery → Battery Use and analyze the list by descending.

To limit background activity:

1. Go to Settings → Applications → Application Management.
2. Select a problem app (such as TikTok or Google Play Services).
3. Click Battery Use and set a Limited Background.
4. Turn off Auto Start and Secondary Start (if available).

Pay special attention to Google Play Services, which often consumes up to 10-15% of its charge per day, to reduce its impact:

• 📱 Turn off Auto-Update apps in the Play Market (settings) → Network → Auto-update).
• 🔍 Disable Background Scanning of Devices in Settings → Google → The device → Scanning.
• 📊 Limit Activity in the Background for Google Play Services via Battery Settings.

For games (such as Genshin Impact or PUBG Mobile), use MIUI with power optimization:

1. Open Settings → Special features → Game turbo mode.
2. Select the game from the list and activate Energy Saving.
3. Turn off Notifications during play and Screen capture.

⚠️ Note: Background restrictions for instant messengers (Telegram, Viber) can lead to delays in receiving notifications. For critical applications (for example, banking) it is better to leave standard settings.

Disabling unnecessary functions: GPS, NFC, 5G and autosynchronization

Wireless communication modules are hidden battery eaters, and even when you're not using them, they continue to scan the environment and consume energy, and we'll look at what can be safely turned off:

The 5G shutdown on budget models (Redmi 12, POCO M6) is particularly relevant, where this module is poorly optimized and drains the battery even in standby mode. To check: switch to 4G and compare screen time every other day of use. The difference can be up to 25%.

Another hidden user is autosynchronization, and turn it off for unnecessary accounts:

1. Go to Settings → Accounts and Synchronization.
2. Select an account (such as Google or Mi Account).
3. Turn off sync for unnecessary data (e.g. Google Photos or Contacts if duplicated).

💡

If you use Xiaomi with two SIM-by cards, disable mobile data on the second card in Settings → SIM-maps and mobile networks, even on standby SIM consumes up to 5% of the charge per day.

5. firmware update and cache reset: when it helps

Often, low screen time is not due to hardware limitations, but to software bugs in MIUI. Regular firmware updates correct optimization errors, but sometimes cause increased consumption. For example, after upgrading to MIUI 14, many Xiaomi 12 users complained about the reduction of autonomy due to the incorrect operation of the service miui.analytics.

To update the firmware:

1. Go to Settings → About the phone → System update.
2. Click Check Updates and install the latest version.
3. After the update, reboot (not a quick restart!).

If after the update, the autonomy deteriorated, try resetting the cache of the system:

1. Turn off the phone.
2. Press the Power button + Volume up to enter Recovery.
3. Select Wipe Cache (use volume buttons for navigation).
4. Confirm the action and restart the device.

For experienced users, a manual rollback to a stable version is available MIUI, if the current firmware contains critical bugs, such as the version MIUI 14.0.4 for Redmi K50 I had a problem with increased nucleus consumption. msm_thermal, corrected in 14.0.6. To check the current version, go to Settings. → The phone. → Version. MIUI.

6.Use of third-party tools: Greenify, AccuBattery and ADB

If standard methods have not increased screen time enough, look for third-party utilities that allow you to optimize the system more deeply, but require caution.

AccuBattery (available on Google Play) is one of the best battery monitoring apps out there.

• 📊 Real battery capacity (compared to factory).
• 🔋 Discharge rate in mA/h for each application.
• ⚡ Optimal charge levels (recommended to be kept in range) 20-80% battery-life extension).

Greenify (requires root rights or ADB activation) is a good way to aggressively optimize your processes, and it freezes the background processes without you knowing them, and it activates Greenify without root:

1. Install Greenify and Minimal ADB and Fastboot on PC.
2. Connect your phone to your computer and enable USB Debugging in Settings → About Phone → MIUI version (click 7 times on MIUI version to unlock Developer Mode).
3. Enter in. ADB Command: adb shell pm grant com.oasisfeng.greenify android.permission.WRITE_SECURE_SETTINGS
4. Restart your phone and add problematic apps to Greenify.

For advanced users, optimization through ADB is available. For example, disabling unnecessary system services:

adb shell pm disable-user --user 0 com.miui.analytics


adb shell pm disable-user --user 0 com.xiaomi.midrop




adb shell pm disable-user --user 0 com.miui.cloudservice

These commands disable analytics collection, Mi Drop service and cloud sync Xiaomi, which can give you a 5-10% increase in screen time. Important: before using ADB, back up your data, as incorrect commands can disrupt the system.

💡

The side of utility like AccuBattery and Greenify is more autonomous, but it requires caution: Start with monitoring (AccuBattery), and go to deep optimization (Greenify/ADB) only if standard methods do not help.

7. Hardware methods: battery replacement and cooling

If software methods are exhausted and screen time is low, the problem may lie in the physical state of the battery. Lithium-polymer batteries degrade over time: after 300-500 charge cycles, their capacity decreases by 20-30%.

1. Enter the phone code in the app: ##4636##.
2. Select Battery Information.
3. Compare Level (current charge) and Health (battery status).

If the battery is under 80% healthy, replacing it can increase screen time by 40-50%. The cost of the original battery for Xiaomi varies from 1,500 to 4000 rubles depending on the model. It is important to use original or certified batteries - cheap counterparts often have less capacity and can damage the power controller.

Another hardware factor is overheating, and at temperatures above 40°C, the battery controller is forced to limit performance, which reduces screen time, to avoid overheating:

• 🌡️ Do not use your phone in direct sunlight.
• 🎮 Avoid long, non-stop gaming sessions (especially in heavy Genshin Impact games).
• 📴 Remove the case during charging or heavy use.
• 🔄 Clean the dust charger connector regularly (use a wooden toothpick).

For active cooling models (such as the Black Shark 5 Pro or POCO F5), check the fan. If it gets clogged with dust, screen time in games can drop by 20-30% due to trottling (a forced decrease in the frequency of the processor).
